I was out logging and I have a tip in stumble. Example, driving with steady tps input, then you go wot. The car will stumble for a sec then clear out. I have tps enrich at .85 and map enrich at .6

You can see it at frame 896, look at the rpm trace you'll see the stumble there.

Any ideas?

thats a ton of enrichment.

Try setting the TPS enrichment to .25, decay to .60

set MAP enrichment to .10 and boost enrichment to 0

See if that helps

Instructions could use a "suggested range" for enrichment adjustments.
Is 10 ok ? or .1 too much ?

Does your spark advance look funny ? 25* at idle , 22* at wot ?

Really loose convertor ? rpm hardly changes through 2nd & 3rd ?

Idle spark is what is programmed into the extender, and 22* is what I command in 3rd.

Its a whole new trans/conv setup. The gov is mismatched which is causing the low rpm shift. The conv is a 9/11 3000rpm stall. I think once I get the shift rpm up, the conv should couple more efficiently.
